To all whom t may concern:

lBe' it known that I, Jnssn A. B. SMITH, a citizen of the-United States,residing in Brooklyn borough, in the county of Kings,

city and State of New York, have invented certain new and usefulImprovements in A Type-Writing Machines, ofV which the following is aspecification. p

This invention relates principally to type- LO writing machines forwriting upon a numleaved with the webs for making the duplicate copies.A machine of this general character is shown and described in the patentto Wernery and Smith No. 1,132,055, dated March 16,1915. In thatmachine, after a section of web,to'composea printed sheet, has

been written, the platen is shifted away from the'usual feed rollers torelease the web and the interleaved carbon sheets; whereupon, bv meansof a carbon sheet holder,the carbon sheets are drawn back along the webinto position thereon for the printing of the next web section; the webitself being drawn forward a measured distance for removal of theprinted section thereof, and the next imprinted section thereof' beingpositioned,with

the carbon sheets therein,` for the printing operation. The same carbonsheets are thus used over and over in the same web form.

Heretofore, in interchanging web forms in the machine, it has, beennecessary at the time of such change, separately to detach the carbonsheets from their holder in removing the web from the machine, andseparately to re-attach the carbon sheets to the holder intheir'interleaved position in the new web.

These operations have involved delay and inconvenience which had oftenmade it desirable to use Atwo or more machines rather than to changewebs freqpently in one ma chine. yIt is an object of the presentinvention yto provide interchangeable holders for the carbon sheets andwebs; so that, with-- out disturbing either the web or the carbon sheetson the holder, vthey may be removed as a unit from the machine; and so'that another web form with carbon sheets already interleaved therewithand mounted on another holder of the same style, may be substitutedwithout delay for that removed. In the preferred form of the invention,the sheet holders may be plates with clips for securing the carbonsheets thereto, and with pins or other means for centering the plates onthe carriage by means" of which the sheet holder is fed toward and fromthe platen.

The carriage may carry guide-pieces to assist the Operator incenteringthe sheet holders thereon. Ordinarily the holders may be removed bysimply'lifting the same from the carriage.

A further object of the invention is to provide, in a machine of thecharacter described, reliable vmeans for guiding the lead-.

and beyond the printing line. It is common in these machines to have aknife blade, located abbve the printing line, for cutting 0E the printedsections of the web. Quite commonly, typewriting machines are providedwith gage plates secured at the front of the machine which have baselines, with scale marks thereon at letter-feed `distances apart, toassist the operator in alining and positioning a line of print forwriting therein. Neither such cutters nor such gages have heretoforebeen used as paper guides in such a way as to assure absolutely certainguidance of the leading edge of the paper at or near the printing point.Such use'of ing edge of the web around the platen, past these parts is afeature of the present 1nvention. To this end, the gage plates referred'to are extended up in the form of y at an intermediate part thereof. Inorderthat the cutter may be usedlto guide the paper beyond the pointwhere the gages cease todo so, the cutter is mounted to be moveddownward, from its normal cutting position, to a point Where itcoperates with the gages to form with the latter a substantiallycontinuous guiding surface for the leading edge ofthe web at the frontof the platen'. 1F or vthis purpose, the; cutter may be j 'fan-foldedlongitudinally,

.away from the feedrolls,

shaft 8, which swings from one to another position, consists of gears29, 30 and 31. The gear 29 is fast to the shaft 26: the gear 30 is fastto the platen shaft, and is of the same size and number of teeth as gear29: andthe gear 31 is loose on the axle 9 around which the platen frameswings, and has a face of sufficient width to simultaneously mesh withgears 29 and30. The driving connection between the shaft 26 and platenis thus maintained in al1 positions of the platen.

In Patent No. 1,132,055, to Wernery and Smith, above refered to, it isshown that in the operation of removing a printed length from the web,and in re-adjusting the web for printing the neXt length, the platen isswung from printing position, to a position so that' the web no longerwraps around the platen, ybut may be moved freely in substantially astraight line from vbaclt to front ofthel machine. the 'platen is inthis position, `the carbon When crosswise fan-folded conditionbeforebeingI fed into the machine to permit ofcompacte ness andconvenience inhandling or it may be fed from a roll.` Itis 4fed into the111echine over a bar 33 at the rear of ra table 34, having side rails 35to which thej bar 33 is securedu rl`hese rails are connected at thefront of the table by a'bar ortie-rod 36 supported by l y u carriage,sotthat the table has letter-feed movemenuwith the platen. The tableframe is furthei-.braced by cross-bars 38 and39,

. from the intersection of which, depends a A y; i) u thence up bracketcarrying a4 roller 41 which rides on a rail 42 carried by -a framework43,' ise cured to or forming part of the main frame of the machine, andwhich supports the table 34 at therear thereof. The web. is led acrossthe table and over the top of a paper guide 44 behind the platen(see'Fig. 4), whence it is passed down betweenfthe platen and thepressure rolls 13 and 1 4, and 'between vthe platen and a air of paperguides or 'spring clips 46,-one o 'which is on each side of the rintingpoint.' From the .guides 46 the ywe passes between tho platen and thelweb-cutting blade 47, onto the aper shelf 48, to which is secured a gagein the form of a bar 49 having adjustably mounted thereon, the,gage-piece 50. The lutter is a bent metal strip having openingsAthrough which the bar 49 passes,

-'of reference to Fig. 4, thatv when the parts are (leading arms 37secured to thev platen and an ofttt portion against which the web can bedrawn in measuring the length of the sheet to be cut from the web at thecutter 47; They gage-piece 50 is adjustable along the bar 49 for anydesired length of sheet, and is held in adjusted position by a thumbscrew 51. -The shelf 48 is screwed to the brace 12, which forms part ofthe swinging platen frame, so that, (as in the machine of the Werneryand Smith Patent 1,132,055,

above. referred to) the paper shelf may swing with the platen inyopening a clear "and straight' path for the web when a sheet is tobecut therefrom, and when re-adjustment is 'to 'be made for the4printing of another sheet. v

The cutter 47 is shownl as a curved bladel having a knife edge 52"against which the webcan be turned' and drawn to cut a sectiontherefrom. Normally it is supported in Fig.g.4 position by a pair ofarms 53 pivotally mounted on the platen shaft 8. Journaled" the sideplate 11 of the platen frame a'. rock shaft 54, fast to which are arms55 pins -56 which work in camslots 57 in plates 58 integral with thevcutter-supporting arms 53. 'A spring 59 secured at one end to one ofthe arms55 and at the=other end to the hub of the adjacent cutter arm53,

holds the `cutter in normal lposition with the pins 56 in pockets ,57lin the forward ends the cam slots 57. It will be noted, on

inl normal position, there is a space 60 between 'the guides 46 andthecutter. Such 'a space vwouldoer an opportunity for the v edge of the webto be fed outside ofthe cutter, instead of between the cutter and theplaten. To eliminate this possibility, the cutter is adapted to. beswung down to F 1g. 5 position to catch the web and to guide it in theproper direction.- In

order that the cutter may have this function as a paper guide, the rockshaft 54, by meansof which it is held in normal position, has, xedthereto, a finger key 61, which may be drawn forward, against the actionof the spring 59, from Fig. 4 to Fig.

5 position. This movementvof the key 61 l, forces the pins 56 rearwardalong the cam grooves 57, thereby rocking the cutter arms downward withthe cutter, until the rear ends 'of the ,cam grooves determine the Fig.

'5 position of the cutter; in which it will be noted that the spacebetween the cutter and the guides 46 has .been closed, lso that the webmust strike the cutter and beguided properly to the shelf 48. Itisnecessary to have the cutter inthe Fig. 5 position only in firstadjusting they forward length of the web for printing; and consequently,duringthis oper-r ation, the cuttermay be held in this position. bysustained pressure on the key 61. As soon as the key is released, thespring 59 returns the' cutter to normal Fig. 4 position.

The paper guides 46, (see Figs. 1 and ll), are spring metal stripsattached to the segment bridge, one on each side of the type guide, andeach bearing on the paper at or about the printing line, and near theprinting point. These guides serve in the double4 capacity of paperlingers and line gages;

and. :t'or the latter purpose, have apertures 64,

f scale markings, the proper-position for any letter to be inserted atthe' printing point is accurately aseertainet'l.

lil/hen the platen trame is thrown up to release the web, and the web isdrawn forward to the gage-piece preliminary to cutting, all friction ofthe several parts on the web has been relieved, with the undesirableconsequence that the web in front ot' the platen may be rocked from trueposition and may be cut other than squarely, unless care is used inproperly alining its leading edge at the gage. To assnre'this correctpositioning of the web at the gage, and to guide the web as it is drawnto the gage, there is mounted, on brace 12 of the swinging frame, aguide in the form of a metal strip (57 which is brought around the upperedge oi the shelll 48, and forward a short distance down the outer faceof the same, to present a smooth guiding surface for one edge of theweb. To secure proper alinement of the web-for cutting, it is onlynecessary, in draw- 'ing the paper to the gage-piece 50,- to keep itsedge in Contact with the guide G7.' To accommodate the guide G7 to websof differcnt widths, the guide 67 is adjustable onthe platen frame. Itis held by a stud (38, which passes from a bloelr 69 on one side of thebraceI 12 through a slot 70, which extends longitudinally of the brace,and through the supporting portion of the guide 67, to be engaged by athreaded head 71, which may be loosened to permit adjustment of theguide, along the slot, and tightened to lock the guide in place. Thebrace is stamped to proide a channel 72 in which the block (i9 may bemoved without interference with the overlying shelfl 48.

lt has been stated that the web is folded longitudinally so that severalcopies may be made at. a time by the use ot' carbon sheets. rlhesecarbon sheets, as above stated. are drawn back front-ther writtenportion ot' the web, into the length thereof next to be writlen. at thetime the web is released and bc- 'I'ore it is cut. For permittingforward lincspace feed ot' the carbon with the web, and for witlulrawingthe carbon sheets from the written. lo the next unwritten section oftheweb. there is provided a carriage to which the rear ends of thecarbon sheets' are ati tached. rihis carriage (see Figs.- .1 and 7)consists of a rectangular plate 74, cut away at 75 for lightness, andhaving at eacheorner an ear 7 6 in which is mounted a grooved roller 77.The rollers 7 7 ride oirflanges 78 ot' the side rails 35 of the papertable, so that the cailriage may be movedtoward the platen by theline-space feed of the latter, and away from the platen by means of ahandle 7 9. 'lhe carbon sheets in the present' invent-ion, are notdirectly attached to the main body of the carriage, but are attached toa plate (see Fig. 6), the center of. which is cut out for lightness andwhich, near each of its corners, has a 'hole 8l, into which a dowel 82on the. bedI plate 7% is adapted to enter when the plate S0 is placedupon the bed plate; the lates 74C and 80, being thus locked toget er.Depending flanges 84 on the plate 8O assist in preventing play. ordisplacement of one plate on the. other. Upwardlf projecting ears'83 onthe bed plate serve as guides for the corner of the plate S0 to assistin registering the dowels 82 with the holes 81 and to enable the plateS0 to be quickly positioned on the bed plate. On the plate 80, at eachside.,Q

of the carriage, is a stepped block SGP. Fin.- gers or clips 85, to eachof which one carbon sheet maybe attached, are secured to the steps S6 ofthe blocks 801. These fingers .which are somewhat less in length thanthe width ot' the web, are staggered; alternate fingers being secured tothe same side of the carriage, so that the fingers may .lie in theoppositely directed fan-folds of the web.

".lhese steps 86 space .the several folds of the web so that the lingerswhich hold theA carbon sheets may not bind the same. The web, as soon as1t reaches the -arriage 74, therefore, becomes interwoven with carbonsheets, the rea-r edges of whichare attached to the fingers 85, and theforward edges volf which are free, except that they are clamped betweenthe folds of the web at the platen by the pressure of the feed rolls 13and lll. Release of this pressure, particularly when the platen islifted far enough to unwrap the web from it, permits et ready retractionoi the carriage, with the carbon sheets, inp depcndently ot' the web.

llcretofore there has been no single holder for all the carbon sheets,which has been readily removable as a unit from the carbonsheetcarriage,- and readily mountable as a unit on that carriage. t isbecause the forms may be frequently changed in ai ma-A chine ot' thischaracter, and to avoid the incmn'enience. on every such change. ofseparately. and at the time of change, detaching and rc-attaching thecarbon sheets, that here Iis provided in the present invention,

carbon holders such as they holder Sti/which are dctachably secured tothe carriage Tl,

. A light'ma'terial, may,

. been temporarily remove inerme and interchangeable thereon. 'Hera 'inchanging the forms, move the carbon sheets plate 80 is -removed as a bonsheets and the kweb thereon.. The 'new form, with a plate`80of its own,andvfwiih `other carbon-sheets already 1n place, 'is 'subform which-hasThe necessity of maintaining two orfmor machines for expedition of workon gvariousforms, is Itherefore obviated. V 'l .The holders 80,

stituted as ai .unit for the which are' preferably-:vof whenthe platenframe is thrown. to'web-releasing position, be lifted bodily froin thecarriage 74 with the web 79, which, (see Fig.

and carbon thereo1i, b means of the handle 6% is riveted to a wing 7 9aon the side of tne carbon sheet holder 80. At'thefrear of the papertable is a device 88, whichprevents possible backward slipping of theweb when the web is'released by 'movement of the platen fram?,v and isnot held by the hand. This device is in the form of a finger pivotedfat89,'to. a lng 90 on the rear cross-tie 33, andl having a bent portion91, oset over the table, so that when the`web is on the table, isturned-down against the web, it exerts suiiicient pressure on thelatter'to prevent backward slipping of the we lt may be held in up ordown position by 88, which normally bears against the back of thefinger, but which, when the finger is its fold, as is common.

" as there is space between turned down againstv the web, bears againstthe surface 88b Yof the finger.

The equivalent of this device has heretofore been one which has extendedfrom one side of the table to the other, and which would thereforeinterfere with the removal and placement of webs with the holders 80, ashereinbefore described. The finger 88, however, in nowise offers suchinterference,

the end of the inger and the other side of the table through which -to.pass the webs in changing the forms.

In order to protect the folded web from being torn bythe Vfree ends ofthe carbonsheet-holding lingers 85, as vthe holder is returned to a newposition relative to the web, guard plates Qr shields 92, are providedfor attachment to the fingers 85. Without such guard plates or shields,the outer corners of the fingers 85 are liable to catch the web,particularly at the Afolds thereof, especially if the web isskewedsidewise, bent or displaced upwardly from the supporting table, orotherwise moved out of its normal straight course (as indicated in Fig.3). The danger of the web being thus torn is increased when the web isperforated along The shield 92, when fin er 85 projects rearwardlyplaced on a e outer edge of thefshield therefrom, and t it isunnecessary-to re-fA from the same; they.; unit w1ththe-carz and thefinger 88 y a spring v is-inclined'inwardly, so that the rearmost endor. point 93 of the shield engage the web` vsome distance inward fromthe old. The

shield thus serves to straighten out or smooth the web, as thecarbon-holder is returned, as well as protecting the web from being tornby abruptly engaging thel sheetholding finger.

The guard plate'92 is preferably made of sheet-metal, and is providedwith lugs 94:', which", when the guard is in position on the finger 8,5,extend alternately on opposite sidesof said finger, the tips 95 .of saidlugs i 9e being offset to engagethe front edge of the linger. Said plateis thus readily 80 slipped on or olii' the said finger, and Visfrictionally held against displacement. The shield or shields maybeapplied to the rearmost finger or ngers at one or both ends of theholder, as conditions may require. As indicated in Fig. 3,*the shieldmay be applied outside of the carbon-sheet.

Variations may be resorted to within the scope of the invention, andportions of the improvements may be used. without others: V Having thusdescribed my invention, l claim: A 1.
